Lighthouse keepers' diets in the early 1900s depended on isolation, supply schedules, and local resources. Core provisions were non-perishable:
Fresh food sources: Fishing (location-dependent), occasional supply ship deliveries, bartering with passing vessels for produce/meat. Some families raised chickens for eggs and meat.
Diets were monotonous but calorie-dense, designed for long stretches without resupply. Nutrition varied by station accessibility and keeper initiative.
